چکیده
A convenient and sustainable protocol for the aerobic oxidation of benzyl alcohols to carbonyl compounds, based on the use of 1,2,4-triazole-type ligands and nickel(II) bromide, is described. This combination leads to the formation of an exceedingly active, enzyme-like system that allows for other oxidative processes, such as benzylic C-H oxidation and oxygen-mediated cleavage of C-C triple bond, a pioneering procedure for transformation of alkynes into carboxylic acids.

متن کاملPeroxynitric Acid: A Convenient Oxygen Source for Oxidation of Organic Compounds Catalyzed by Polyimide-Supported Manganese (III) Tetrakis(4-methoxylphenyl)porphyrin Acetate
In this work, a polyimide (PI) containing triazole units was synthesized using 3,5-diamino-1,2,4-triazole and pyromellitic dianhydride in N-methyl-2-pyrrolidinone. This polymer was used as the support of manganese (III) tetrakis(4-methoxylphenyl)porphyrin acetate to attain a heterogeneous catalyst; namely Mn(T4-OMePP)OAc@PI. The synthesized PI and Mn(T4-OMePP)OAc@PI were characterized by di...
